The present invention relates to new and useful improvements in gates and has for its primary object to provide, in a manner as hereinafter set forth, a gate embodying a novel construction, combination and arrangement of parts through the medium of which said gate may be opened by a vehicle approaching the same and closed by gravity after the vehicle has passed, thus obviating the necessity for a person getting out of the vehicle to perform this task.

Other objects of the invention are to provide a gate of the aforementioned character which will be comparatively simple in construction, strong, durable, reliable in operation and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:-

Figure 1 is a view in side elevation of a gate constructed in accordance with the present invention, showing said gate closed.

Figure 2 is a side elevational View, showing the gate open with a vehicle about to pass therethrough.

Figure 3 is a view in front elevation of the gate in closed position.

Figure 4 is a view in front elevation, showing the gate in open position with a vehicle passing therethrough.

Figure 5 is a view in top plan of the gate.

Figure 6 is a detail view in perspective of one of the counter-weights.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a pair of tubular metallic posts 1 which are anchored in concrete 2. A concrete landing 3 extends between the post anchorages 2.

On opposite sides of the posts 1 are concrete foundations 4% which are embedded in the ground. The reference numeral 5 designates generally depressible platforms which are hingedly mounted at their outer ends, as at 6, on the foundations or bases a. It will thus be seen that the depressible platforms 5 are mounted for swinging movement in a vertical plane, the free inner ends thereof resting on the landing 3 between the posts 1 when said platforms are in lowered or open position, as illustrated to advantage in Figure 2 of the drawings. Each of the depressible platforms 5 comprises a pair of spaced, parallel troughs 7 over which the wheels of the vehicle pass and between which braces 8 extend. The braces 8 are secured to the bottoms of the troughs 7 for supporting said troughs under the weight of the vehicle when the gate is in open position. Also, the braces 8 function as guards to prevent the passage of stock between the troughs '7 when the gate is closed. Approaches 9 are provided on the bases 4 at the hinged outer ends of the troughs 7, said approaches including converging side! guides for directing the wheels of the vehicle into the troughs, as best seen in Figure 5 of the drawings.

The posts 1 are bifurcated at their upper ends and journaled therein are grooved pulleys 10 over which cables 11 are trained. Weights 12 are suspended from one end of the cables 11 and slidably engaged with the posts 1, one side of said weights 12 being concave (see Figure 6) to conform to the posts. The other ends of the cables 11 are connected to the free inner ends of the troughs '7 of the depressible platforms 5 by branches 13, said branches 13 being secured to the ends of the comparatively long innermost braces 8 thereby preventing fouling of the vehi- 0 cle as it passes.

The reference numeral 14 designates a guard rail which is pivotally mounted at an intermediate point on the upper portion of one of the posts 1, as at 15. As will be apparent, the guard rail 35 14, when in operative position, extends between the posts 1. A counterweight 16 is provided on one end of the guard rail 14. A suitable catch or support 17 is provided on the other post for receiving the other end of the guard rail 14. '90 Spaced pickets 18 depend from the guard rail 14. The counterweighted end of the guard rail 14 is connected by a cable 19 with one of the depressible platforms 5 for actuation to open position thereby.

Briefly, the operation of lows:-

The depressible platforms 5 are normally maintained in raised position by the weights 12, as shown in Figures 1 and 3 of the drawings. When '100 an automobile passes on to one of the platforms 5, said one platform is swung downwardly thereby, thus elevating the weights 12 and permitting the other platform to swing downwardly simultaneously. As the platforms 5 are thus lowered, the guard rail 14 is swung upwardly to open position through the medium of the cable 19, as clearly seen in Figure 4 of the drawings. After the automobile has passed, the weights 12 raise the platforms 5 to closed position and the guard 1110 '95 the gate is as folrail 14 is thus permitted to return by gravity to its lowered or closed position.

It is believed that the many advantages of a gate constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:-

1. A gate of the class described comprising a pair of spaced posts, a pair of longitudinally aligned platforms having their inner ends spaced apart and located adjacent the space between the two posts, means for hingedly supporting the outer ends of the platforms, laterally extending projections connected to the sides of each platform adjacent the inner end thereof, a pulley at the upper end of each post, a cable passing over each pulley, a pair of branch cables connected to the inner ends of said first mentioned cables, the

ends of said branch cables being connected to the projections, weights connected to the other ends of the first mentioned cables, a guard rail pivotally connected to one post, a keeper member carried by the other post for receiving the free end of the guard rail, and a cable connecting the hinged end of the rail to a projection.

2. A gate comprising a pair of spaced posts, pulleys at the upper ends of the posts, a pair of platforms longitudinally aligned and having their inner ends spaced apart and located adjacent the space between the two posts, means for hingedly supporting the outer ends of the platforms, each platform comprising a pair of channel members spaced apart and brace bars connecting the pair together, the innermost bar having its ends extended beyond the channel members, a cable passing over each pulley and having its inner end branched and connected to the two adjacent extended ends of the said brace bars, a weight on the other end of each cable having a recess therein for receiving portion of a post.
